摘要:
According to one embodiment, there is provided an electric power conversion apparatus provided with a plurality of converters and inverters (11, 21, 12, 22; 11, 21, 12, 22, 13, 23) that share direct current voltage sections, each of the direct current voltage sections independent of other direct current voltage sections, and output sides of the inverters (21, 22; 21, 22, 23) connected to each other. The apparatus includes a control device (10) configured to obtain a cross current amount between the inverters by performing predetermined axis-conversion on a detection value of a cross current between the inverters, and control an output voltage or an output current of the individual converters or the individual inverters based on the cross current amount.

According to one embodiment, a test apparatus (10) for a variable speed controller (20) is provided. A prime mover computation unit (16) computes behaviors of the prime mover (6), using a state quantity regarding the prime mover (6) and a predetermined transfer function. An AC machine computation unit (15) computes behaviors of the AC machine (5), using a state quantity regarding the AC machine (5) and a predetermined transfer function. A power converter computation unit (14) computes behaviors of the power converter (4), using a state quantity regarding the power converter (4) and a predetermined transfer function. Each of the computation units uses computation results of other computation units.
